10 points CASE STUDY PEFORMING ROR ANALYSIS FOR 3D PRINTER AND NOT TECHNOLOGY Background Software used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop holows, shells, and tree supports to save development time. Network printing for use on multiple machines and at different locations globally is available. New software called it it is being beta tested that will allow lloT-type (Industrial Internet of Things) connections between machines at distant locations. When onboard monitoring sensors detect that a part is about to folloritis time to replace one of several high-profile parts, the IT il software will automatically queue the part's manufacturing code onto a 3D printer that is detected to be local die or ready. The company believes it can design and produce the IT il software, the 3D printers, and the accompanying computer equipment necessary to place this technology in a wide variety of harsh environments.chemically toxic to humans, in fight, underground in mines, on the ocean floor, in war-torn areas, etc Information For this case, we will analyze the available computers that can provide the server function necessary to make this interlinking walable and successful. The fest cost and other parameter estimates, including expected contribution to annual net cash flow, are summarized below.

The PW for server 3 (5 years) LCM cash flow 62,223.89 4. Based on the PW analysis which option should be selected ? 8- The ROR for each option, answer the below questions 1. The ROR for servert over 3 years operation equal = 2% 2. The ROR for server2 over years operation equal = 15% 3. The ROR for server over 5 years operation equal - 14% 4. Based on the ROR for each option which option we should select C-Use incremental ROR analysis between server 2 and server 3 to decide which is the best option at MARR - 12% Answer the below questions 1. As per the Descartes rule of signs for the NCF between servers 283, what is the maximum number of real number Delta. ;* that exist 2. As per the Norstroms criterion, is there a one real-positive Delta * exist (enter yes or no)? 3. What is the value of Delta i between server 2 & 3 if exist? 4. Based on the incremental analysis which option we should select if incremental analysis is applicabile? 10 points CASE STUDY PEFORMING ROR ANALYSIS FOR 3D PRINTER AND NOT TECHNOLOGY Background Software used in 3D printer systems manufactured by Spectrum LASER Corp. is currently able to automatically develop holows, shells, and tree supports to save development time.
